What are the key features of G5Q1A12DC?
- SPST-NO contact configuration rated for 10 A AC and 5 A DC switching capability
- 12 V DC coil with 720 Ω coil resistance enabling low-power driver circuit control
- Through-hole PCB mounting for robust mechanical attachment in demanding environments
What is G5Q1A12DC used for?
The G5Q1A12DC is widely used in home appliances, industrial control panels, and HVAC systems where a 12 V DC logic signal must switch mains-voltage AC or low-voltage DC loads. Its compact through-hole design suits PCB-mounted relay modules, power control boards, and PLC output stages requiring a 10 A switching element. The SPST-NO contact form makes it ideal for motor starters, lighting controls, and solenoid valve drivers needing a normally-open switching relay.

Frequently Asked Questions
What coil voltage and resistance does the G5Q1A12DC require for reliable energization?
The G5Q1A12DC requires a 12 V DC coil voltage and has a coil resistance of 720 Ω, drawing approximately 16.7 mA at nominal voltage. The driver circuit must sustain this continuous current to keep the SPST-NO contacts reliably closed throughout the application duty cycle.
What AC and DC load ratings can the G5Q1A12DC contact safely switch in a control circuit?
The G5Q1A12DC SPST-NO contact is rated to switch up to 10 A at 250 V AC for resistive loads or 5 A at 30 V DC, making it suitable for mains-voltage appliance control and low-voltage DC motor switching. Inductive loads require snubber circuits or contact derating to protect relay life.
In what scenario is G5Q1A12DC a suitable alternative to a solid-state relay for switching an AC heating element?
G5Q1A12DC is preferred over a solid-state relay when zero-voltage-switching is unnecessary, cost is a priority, and the AC load draws under 10 A at 250 V AC. Its 12 V DC coil makes it directly drivable from a microcontroller output stage using a small transistor or FET, with near-zero on-state voltage drop unlike SSRs.
